IIREARM FOR KILLING CATTLE.

Application filed December s, 1927. Serial m. 288,610.

This invention relates to firearms, and its general object is to provide a firearm primarily designed for use in killing cattle in a humane manner and with safety and con-.

venience to the user.

A further object of the invention is to provide a firearm of the character set forth, that is simple in construction, inexpensive to manufacture and; efiicient in operation and service.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to the accompanying 2o drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a longitudinal sectional view taken through one form of the firearm which forms the subject matter of the present invention.

Figure 2 is a front view 'of a portion thereof.

Figure 3 is a sectional view takep apre Fi re 4 is a fragmentary longitudinal secti fi al view taken through a modified .form of the invention.

Referring to the drawings in detail, the

reference numeral 1 indicates one section of the barrel and 2 the other section. The section 2 is provided with a threaded extension 3 adapted to be received in a threaded recess formed in the section 1 for securing o the sections in barrel formation as shown.

The opposite or outer end of the section 2 terminates in an outwardly flared portion indicated by the reference numeral 4. From this construction it will be apparent that the firearm is loaded by separating the respective sections and introducing a cartridge in the section 2 with the flange of the cartridge engaging the end of the threaded extension 3. The bottom of the recess is grooved to accommodate the flanged end ee istration with the bore of the section 2 when the respective sections are secured together.

instrumentality of an annular flange 9 which is adapted to engage the flange 7 as best shown in Figure 1 of'the drawmgs.

The section 1 has arranged in its bore adjacent the upper end thereof an annular groove 10 adapted to receive the rounded portion '11 of a resilient member which includes spaced arallel fingers 12 extending from the roun ed portion as best shown in Figure 3 of the drawings. These fingers 12 extend through an o ening formed in the section 1 and into a siilistantially L-shaped slot formed in the cap 8. The fingers are normally received in the horizontal portion 13 of the slot but are capable of being moved in the vertical portion 1.4 thereof for a purpose which w1ll be presently apparent. Depending from the top 15 of the cap is a rod 16 which has its free end dis osed for slidable movement in a sleeve 1 ar-, ranged in the section ,1. The sleeve 17 is provided with a reduced upper end to provide a shoulder for the purpose of accommodating one end convolution of a coil spring 18, while the opposite end engages the top of the cap. The sleeve. 17 is further provided with a recess communicating with an opening 19 at its upper end,'and secured in the recess is a resilient latch member 20 having a. projection 21 formed with its upper end andextending into the bore of the sleeve to normally engage the upper end of the firing pin rod 22 which is enlarged intermediate its ends for the purpose of providing a shoulder 2-3 and formed adjacent the lower end of the firing pin rod is a collar 24. Arranged between the lower end of the sleeve 17 and the collar 24 for surrounding the firing pin rod is a coil spring 25. The firing pin rod has also surround-. ing the same a check spring 26, while depending from the rod is a firing pin 27. g In Figure 4: I have illustrated aslightly modified form of invention which includes a rotary member 28 provided with cartridge chambers 29 disposed concentric of the center of the member which is formed with an opening to accommodate a shaft pin 30 rotatably receiving the member 28. The

shaft pin 30 is secured in any well knownso as to'stop the cartridge chambers in alignment with the bore of the barrel in the manner as clearly shown in Figure 4 of the drawings.

From the above description and disclosure of the drawings, it will be obvious that I have provided'a firearm, that will be exceediingly useful for killing animals in a safe and humane manner, and when the cap member 8 is rotated for disposing the spring fingers 12 in the vertical portion 14 of the slot formed in the cap member, it will be apparent that the cap member can be slid longitudinally on the section 1 of the barrel. Upon shoving the cap member against the tension of its spring 18, the rod 16 will engage the projection 21 which as shown is provided with a rounded upper end. This movement will release the firing pin rod and cause the engagement of the sleeve 17 with the shoulder 23 thereof and due to the function of the respective coil springs 18 and 25 and the check s ring 26, the firing pin will be given a quic movement and engage the cap of the cartridge accordingly, causing the latter to explode.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is:

1. A firearm of the character described comprising a barrel, a flared portion formed on one end of said barrel, a cap member mounted for slidable movement on the op 0,- site end thereof, a rod extending centra ly from the cap member, means arranged in said'barrel for receiving a cartridge, a spring pressed sleeve for receiving the rod, a spring pressed firing pin rod havin a portion arran ed in the sleeve, a late member normal y engaged with the firing pin rod, a firin pin extending from the firing in rod, and ocking means for the cap mem er.

2. A firearm of the character described comprising a barrel, a flange formed on one end of said barrel, an outwardly flared portion formed on the opposite end thereof, a cap. member provided with a flange for nor mally engaging the flange first mentioned, and being formed with a substantially L- shaped slot, lockin means arranged 1n a groove formed in t e barrel and extending through the same into the slot. of the cap member, a sleeve mounted for slidable movement in said barrel and. having a reduced upper end, a-rod extending from said cap member, a spring surrounding the-rod and being engageable with the sleeve, a spring pressed latch control firing pin rod arranged in said barrel and being operated by engagement of said sleeve therewith, and a firing pin extending from said firing pin rod.

3. A firearm of the character described comprising a barrel, a flange formed on one end thereof, a flared portion formed on the opposite end thereof, a cap member including'a flange engageable with the flange of the barrel and being slidably mounted on the latter, a rod extending from the cap member,

a sleeve arranged in said barrel for slidable movement, a coil spring surrounding said rod and being engag'eablc with said sleeve, a latch member carried by said sleeve, a spring pressed firing pin rod mounted for movement in said barrel, a shoulder formed with slidable movement-0n said barrel, a rod extending from said cap member for releasing the latch of the firing pin rod, locking means for said cap member, and a firing pin extending from said firing pin rod.

5. A firearm of the character described comprising a barrel, a flange formed on one end of said barrel and extending outwardly therefrom, an outwardly flared portion formed on the opposite end of said barrel, a

cap member provided with a substantially L-shape'd slot and mounted for slidable move- 'ment on said barrel, a rod extending from the cap member and having a free portion disposed in the barrel, a spring pressed sleeve slidably receiving said rod, a firing pin rod .formed with a shoulder and having a portion arranged in said sleeve, a latch carried by said sleeve and being normally engaged with the firing pin rod, a collar carried by said firing pin rod, a coil spring having its end convoluti'ons enga m said collar and sleeve respectively, a c ecIr spring for said firing pin rod, a firing pin extending from said firing pin rod, a resilient member carried by the barrel, fingers formed with said resilient member and'arranged in the slot of the cap member for controlling the movement of the latter, and a cartridge receiving means carried by said barrel.

In testimony whereof I aflix m si aturc.
